Radena radiators are heavy-duty heating equipment. Today, these units are among the most popular on the market. And this cannot be called an accident or luck. After all, the batteries of this manufacturer have earned popularity for their high quality and long service life. These products consist of separate sections, which are interconnected by paronite gaskets and steel nipples for connection. The internal part is a pipe frame based on carbon steel. By purchasing this equipment, you can count on a long service life, which is ensured by eliminating the contact of the aluminum shell with water. The manufacturer has created conditions that exclude electrochemical corrosion.
Technical characteristics of sectional bimetallic radiators of different models
Radena bimetallic radiators, sold as sectional products, are designated as CS 150, CS 350, and CS 500/VC 500. All of them are capable of operating at a pressure of 25 atmospheres, the test pressure for all three models is 40 atmospheres, while burst pressure is equivalent to 90 atmospheres. The coolant temperature is also no different and is 110 ° C; this cannot be said about the thermal output of one section. In the first case, the parameter is 120, in the second - 135, while in the third - 185 W.
Aluminum heating equipment
Although many experts suggest that buyers purchase Raden, this is not a mandatory rule. Aluminum as a manufacturing material is quite good in terms of thermal output and a number of other important characteristics. If the work environment allows, the application is justified. Some rules still need to be taken into account.
Aluminum radiators from Radena are used in systems based on water heating. Buildings – administrative, residential, public. Low-rise buildings are suitable.
Manufacturing process and cost
It's time to talk about more serious things. Let's start with a little information, which is that Raden aluminum heating radiators are made from a number of sections. The latter are cast under high pressure. Then they are combined into a single whole. For this purpose, steel nipples and special types of gaskets are used.
Aluminum radiator Radena 500.
Products are painted using epoxy polyester. A couple of layers are applied. If you are well versed in various technical subtleties, we will add that when creating a protective coating, two methods are used. The first is cataphoresis. The second is electrostatic spraying. We are talking about enamel in powder form. At the very end, the product is coated with a paint composition that belongs to class A.
You need to know the following - both the manufacturing and painting of Radena aluminum radiators are done at an acceptable level. In total, there are two types of aluminum products to choose from – R350 and R500. Price R350 – from approximately $11.3 per section, R500–$11.8.
Specifications
The basic properties of R350 and R500 are not very different. We will consider the first option. If the R500 is different in some way, we will explain it separately. Normal operation of radiators is guaranteed at a coolant operating pressure of 16 atm. As for the test one, it is 24 atm. The burst pressure is 50 atm.
The thermal output of one section is very high - 165 W. The R500 model has slightly more - 192 W. In order for heating equipment to last a long time, the coolant temperature should not exceed 110 degrees. Plus per liter of working fluid more than 0.02 mg of oxygen is prohibited
It is worth paying attention to the pH. Acceptable value – from 6.5 to 9

One section of the product holds 0.275 l (R500–0.330 l). The weight also varies to some extent. R350 – 1.05 kg, R500 – 1.35 kg. The section height is 431 mm and 581 mm, respectively, for different models. The center distance is 350 mm and 500 mm (hence the indices in the name). The remaining indicators are again the same. For example, the depth of the radiator section is 85 mm. Width – 80 mm. The inlet holes for connection have a diameter of 1 inch. White color.
We believe that the information provided is more than enough to superficially evaluate aluminum products. Let's move on to a more interesting option. We are talking about Radena bimetallic heating radiators, which are even more versatile.
Dimensions
When choosing such equipment, you should also count on the fact that each model has its own height. For these options, these parameters are 241, 403 and 552 mm, respectively. The distance between the axles is also different and is equal to 150, 350 and 500 mm for each model. When purchasing Radena heating radiators, which are sold under the brands CS 150, CS 350, as well as CS 500/VC 500, you must count on a certain depth and width of the sections. For the first model these dimensions are 120 x 74, and for the second and third – 85 x 80 mm.
Reviews about the features of Radena radiators
produces aluminum and bimetallic radiators. The first of them have a certain shape of vertical and horizontal collectors, which are a wide ellipse. This allows for the least resistance to water flow, so the heat transfer from each section is quite good. The collector itself does not experience such high loads, this helps to extend its service life and increase reliability.
The second feature of such batteries is the thickness of the walls of the vertical tubes; for this manufacturer this parameter is always greater than 1.9 mm. It cannot be said that bimetallic radiators are characterized by less reliability. Bimetal in this case is complemented by thick-walled steel collectors. The steel used is high-carbon; because of this, the hydrogen index can vary within quite a wide range; it varies from 6 to 10.5 units.
Additional benefits
Another feature is two-stage coloring. At the first stage, all sections are processed, they are cleaned, and then degreased, preparing the painting surface. Each section, outside and inside, is covered with a layer of paint that protects the material from corrosion. There are many little things that add advantages in favor of radiators. Users note that the self-aligning graphite intersection gaskets provide a complete seal. The carving is not filled with paint; it is distinguished by jealousy and depth. Home craftsmen also note the security of the ends as a plus; after unpacking the batteries, they can be installed immediately.
Reviews of aluminum radiators of the "Radena" brand
Aluminum radiators "Radena", reviews of which will allow you to understand whether it is worth purchasing this or that model, do not have a wide range. They are presented to the consumer in two modifications, one of them has an interaxal distance of 350, while the other has 500 mm. According to users, the price for one section of such batteries varies from $11 to $12. Batteries are manufactured with side connections, and for stable operation an automatic air vent or a Mayevsky valve should be installed.
Consumers are advised to install mud traps or filters if the coolant is rich in impurities. Aluminum radiators "Radena" are recommended for installation in private houses that are heated by an individual system. Here you can independently adjust the pH level and pressure. All users who installed these radiators in apartments note that they are faced with problems that are expressed in frequent changes in pressure and the negative impact of impurities in water on the materials of the product. In addition, changing just one battery can completely unbalance the system, and the apartment will become colder. It is necessary to clarify what pressure in the system is normal.
Advantages and disadvantages
Raden radiators are primarily attractive due to their aesthetic design. Even without knowing about their technical characteristics, buyers stop at the products, attracted by the smooth surface and thin lines. The sections have vertical fins that enhance convection currents. Among the main advantages of the products:
- Cast radiators are reliable. They have one weld seam.
- The internal and external surfaces of the products have undergone corrosion treatment and two-stage painting.
- Materials safe for human health are used in production.
- Aluminum and bimetallic batteries provide high heat transfer.
- The equipment is resistant to pressure and water hammer.
- The durable coating allows the batteries to be used in heating systems with a pH value of 6.5-9.
- Painting is carried out in an even layer, it does not fade under the sun's rays.
Raden radiators can be installed in a central heating system instead of cast iron ones, where water hammer is possible.
At the factory, products are packaged in plastic film and cardboard boxes. Goods are transported to stores without damage.
Flaws:
- Aluminum models are sensitive to the condition of the coolant. They are not recommended for multi-storey buildings with central heating.
- The cost of Italian brand products is not available to all buyers.
Heating devices have received many positive reviews. They are recommended by experts and homeowners.
Radena products are radiators that can be installed in residential, commercial, industrial or office spaces. They comply with safety standards adopted in Europe and Russian standards. Sectional batteries are designed for installation in single-pipe and two-pipe closed heating systems.
Technical characteristics of Radena aluminum radiators
Radena 500 radiators are batteries in which the distance between the axes corresponds to 500 mm. However, this characteristic is not the only one you should pay attention to when purchasing a device. It is important to note that such batteries will function normally at a pH of no higher than 9; a value of 7 units is considered optimal. The operating pressure is 16 atmospheres, but the batteries can withstand up to 50 atmospheres. This reserve should be sufficient for emergency situations. But if serious pressure drops are quite frequent in the system, then it is best to install bimetallic radiators.
The right choice of radiators
The number of sections required to heat the room area
When choosing heating system devices, several significant factors are taken into account:
- Maximum operating pressure - the value is indicated in the product data sheet.
- Type of heating system - autonomous or centralized. It should be taken into account that the centralized system is subject to pressure surges.
- Heat transfer of one section - this characteristic allows you to calculate the number of sections required to heat the room.
- Coolant acidity indicator - the composition of the coolant affects the life of the batteries. Hard water with a high salt content accelerates corrosion processes.
- Appearance of radiators - devices should fit organically into the interior of the room.
When choosing a product, you should pay attention to the markings on the packaging. There are many fakes of the Italian brand on the market. The original products have a barcode of the country of origin, a label indicating that they have passed the quality control department, and information about the type of radiator.
Reviews of Radena brand bimetallic batteries
You can follow the experience of many buyers and purchase a Radena radiator for your home. The bimetal in its base will prevent contact of water with aluminum, because the characteristics of central heating systems are far from normal. Aluminum is a reactive metal and at high pH levels it can corrode, causing leaks.
The second reason, which indicates the advisability of using bimetallic radiators, is expressed in their increased strength. Aluminum and its alloys can be called soft metals, and pressure changes can damage the material. Moreover, some manufacturers are trying to save money by making the collector walls thin. Whereas if steel of even a small thickness is used, it can withstand impressive pressure.
As buyers emphasize, in batteries, steel collectors are connected by welding, a vertical tube is welded into the collector. However, steel has a low thermal conductivity coefficient, so aluminum is fused onto it to create duct fins. As a result, it is possible to obtain a bimetallic section, which is characterized by low chemical reactivity, impressive strength and excellent thermal power.
Considering Raden radiators, one can highlight their advantages over the products of many other companies. The latter sometimes produce batteries in which the steel is located only in a vertical tube. In such batteries, heat transfer is higher, but the coolant is in contact with the material. These products may not be suitable for all networks. As for Radena, it produces only full bimetal, using high-carbon steel. According to users, this is why the operating pressure of such products is 25 atmospheres, and the warranty period reaches 25 years, and the ambient temperature is equivalent to 100 °C. Center distances are 150 and 500 mm. Some buyers are put off by the price of radiators, which is approximately $14, but this cost is justified, because such batteries are ready to last even longer than the guaranteed service life.
Why else is it worth choosing Radena brand heating radiators?
Radena radiators have been manufactured in Italy for over 30 years. By purchasing this equipment, you can count on the fact that it is of high quality and adapted for use in Russian conditions. "Radena" are radiators, the manufacturer of which takes care that the technical specifications of the products correspond to the heating systems of the countries where they are supplied. For example, aluminum radiators manufactured for Russia are capable of withstanding pressure of up to 16 atmospheres, which allows these batteries to be used even in high-rise construction. In addition, they have an attractive design and modern appearance; they can fit into the interior of any room. The main fin profile with a rounded top ensures safety from injuries.
